To all ZU7'L0777/ it may concern:

7 Be it known that I, EDWIN J. PRINDLE, of Washington, in the Districtof Columbia, have invented certain new and useful Improvements in Lasts;and I do hereby declare that the following is a full, clear, and exactdescription thereof,reference being had to the accompanying drawings,inwhich Figure 1 represents a partial vertical longitudinal sectionalview of my last. Fig. 2 represents a partial horizontal longitudinalsectional view of thelast shown in Fig. 1, the section being taken onthe line a: as of said figure. Fig. 3 represents a vertical transversesectional view, looking forward, of the last shown in Fig. 1, thesection being taken on the line '3 y of said figure and the lockingpiecebeing omitted. Fig. at is a perspective View of the locking-piece. Figs.5, 6, and 7 are a side elevation, a front elevation, and a top planview, respectively, of the part comprising the heel-part plate, web, andjack-pin socket. Figs. 8, 9, and 10 are a side elevation, a frontelevation, and a top plan View, respectively, of the fore-part plate.Figs. 11, 12, and 13 are a side elevation, a front elevation, and a topplan view, respectively, of the removable wedge. Fig. 14 is aperspective View of a modified form of wedge,its combined handle andflange being shown before attachment to the wedge. Fig. 15 is aperspective View of a modified form of last, and Fig. 16 is aperspective view of the lockingpiece used in the last shown in Fig. 15.

The object of this invention is to providea last designed especially foruse in lasting and similar machines, but whose features of constructionare susceptible of embodiment in followers, stretchers, display-formsfor shoes, &c.; and to this end my invention consists in the last,follower, stretcher, display-form, or like structure having theconstruction substantially as hereinafter set forth.

In making my invention my aim has been to provide a last capable of easyseparation from and insertion into the shoe, which shall have amplestrength, and to provide a last which shall embody any or allof thefeatures of being easily unlocked at the instant of the separation ofthe last and shoe, such unlocking being possible without the use of thehands, so as to leave them free for manipulating the shoe, of beingautomatically ex tensible and self-locking, not only against collapse,but also against strains tending to move its parts farther apart thantheir extended positions, of having a separable or easily-removable forepart, and of having a construc tion by which anvil-heel seats of varioussizes and shapes can be used.

My improvements are capable of application to various forms of lasts;but it will be sufficient to illustrate the invention to show the sameembodied in ahinged last. In Figs. 1 to 13, inclusive, I show such alast that is divided, so that the fore part A has a rear face A, theplane of which is preferably perpendicular to the length of the last;The heel part B has a short vertical face B at its front lower portion,which face when the last is extended abuts against the rear face A ofthe fore part A, and the front face 13 of the heel part above the shortvertical face inclines backward and upward in a transverse plane. Theopposite surfaces of the fore and heel parts may, however, be given anyde sired shape or inclination, so long as a recess is formed betweenthem when the last is extended. My connection between the fore and heelparts causes the heel part B to turn on or substantially on the line bwhere the planes of the vertical and inclined portions B and B meet orintersect the planes of the front face of the heel part and enables thatline b to be located low in the last, thereby securing the greatshortening of the last that is due to the low center of movement of theheel part. The connection I employ between the fore and heel partsconsists, in general, of two substantially-vertical longitudinal plates,one of which, (J, is attached to the fore part and extends across therecess between the fore and heel parts and preferably, although notnecessarily, into a slot B in the heel part, and the other of whichplates D is secured to the heel part B, overlaps the forepart plate 0,and preferably, although not necessarily, extends into a slot A in thefore part. These plates C and D are connected together, preferably by ahinge connection, at or about the line of meeting between planes of thetwo surfaces B and B on the front face of the heel part B. The verticalsurfaces A and B on the fore and heel parts abut below the hinge-centerand prevent the portions of the last parts above the hinge-center frommoving farther apart than their normal pos'ition. The plates and' D,which are connected to the parts of the last and extend into or acrossthe recess between the parts of the last when the last is extended, canbe made to abut against each other and not overlap when the last isextended, or they can overlap and not extend into recesses in the partsof the last opposite those to which they are attached, respectively,when the last is extended, or one of such plates can span the recess andenter a slot in the opposite part of the last while the second platemerely extends into the recess, but not into a slot in the part of thelast opposite that part to which the second plate is attached when thelast is extended, or a single plate can be used, which plate can extendacross the recess and into a slot in the part of the last opposite thatto whichsaid plate is attached when the last is extended, or a singleplate can be used, which plate merely extends from one wall of therecess toward the opposite wall of said recess, but does not enter aslot in said opposite wall, means being provided whereby the plate canengage said opposite wall when the last is extended. My inventionincludes all of the above-stated constructions and includes any lasthaving a portion removed between the fore and heel parts, forming arecess lying transversely of the last when extended and having a plateor other strengthening part having considerable width, which plate orother strengthening part projects from one wall of the recess or isattached to one of the parts of the last, and said last being so con-'st-ructed that said plate or strengthening part can directly orindirectly engage the wall of the recess or the part of the lastopposite that wall or part from which it-projects or to which it isattached, respectively. Instead of a single pair of plates any number ofpairs which extend into or across the recess or any number of suchplates used singly can be employed. While I have shown the plates asperpendicular to the axis of motion b, such plates can be placed in thelast so that they are parallel to the axis of motion 19 andextend'across the recess between the last parts and are curvedconcentric to the axis of motion I).

strengthen the lastgive great strength tothe last to resist racking ortwisting strains, such as occur during lasting, and when locked to eachother or to the part of the lastopposite the part to whichthey areattached they furnish with the use of a minimum'amount. of metal ormaterial a maximum strength to resist either strains tending to forcethe parts of the last apart beyond their normal extended positions orstrains tending-to collapse the 'last.

the parts of the last, which parts have greater vertical than horizontalwidth at the instep, and of attachment to the jack-pin socket. The foreand heel part plates are preferably formed separate from and areattached to the last parts, and they are preferably formed of metal; butthey can, if desired, 'be integral with the last parts.

To attach the fore-part plate 0 to the fore part, said plate is providedwith an arc-shaped flange G on its outer face-11 e., the face op.-posite to the heel-part plate-and this flange C fits into an arc-shapedgroove A formed in the wall-of a slot A in the fore part A. Teeth O and0 formed on the arc-shaped flange O, bite into the wood in the groove Aand prevent the flange from turning in the groove. The plate 0 is heldwith the flange Oin the groove A by a wedge E, that also occupies theslot A and that is semicircular in form and tapers from top to bottomand from the rear edge toward the front, although itis not necessary tohave it taper in both these directions. The wall A of the slot A in thefore part is inclined tofit the wedge E and is out out at a to permitsufficient lateral movement of the heel-part plate, so that thearcshaped flange on the fore-part plate can enter the slot A until it isopposite the arc-shaped groove A The opposite wall of the slot A and thewedge E are cut out to permit proper movement of the enlarged ends ofthe arms on the locking-piece. The wedge E is also reoessed at e topermit movement of the heelbent up into a spring-handle E a portion ofwhose free end E engages a notch O inthe fore-part hinge-plate 0, thuslocking the wedge E in place and through it the fore-part hinge-plate G.The flange E and springhandle E can, if desired, be formed of a strip Cof spring-steel, as shown in Fig. 16, and may be fastened to the wedge Eby having holes E and E formed in it and lugs E and E formed on thewedge E, the lugs being passed through the holes and headed over. Thewedge E can be inserted and removed by hand, thus providing convenientmeans for readily removing one fore part and substituting another. Thedifference between lasts of the same size, but of different styles, liesalmost entirely in the shape of the toe, and one heel part can thus withmy means for detachably securing the fore part thereto be used with anynumber of fore parts. The

cost of adapting a last to a different fashion is thus reduced to themere cost of a fore part. Moreover, the wear on a last comes almostentirely on the fore part, especially when the anvil-heel seat is used,so that by my mechanism the life of the last is increased many timessolely at the cost of new fore parts. My detachable fore part thusresults in great economy.

The fore-part plate 0 is hinged to the heelpart plate D by a rivet F,which occupies-oppositely-countersunk holes in said plates, its endsbeing preferably flush with the outer faces of said plates, as showninFig. 3. Each of these plates Oand D is provided with aslot G above thehinge, each of which slots G and G has a straight wall G on the sidetoward the outer edge of the plate and an. opposite wall G that isstraight at the top only for a very short distance,from which point itsweeps out in a compound curve or in an oblique line, as preferred, andaround to the straight wall. One of the slots G may, if preferred, haveboth of its walls straight.

In the heel part a vertical hole H is bored to receive the jack-pinsocket I. Ahorizontal and a vertical saw-cut K and L are made, thusremoving material to form a socket for the anvil-heel seat N, and avertical slot B is made from the jack-pin-socket hole H forward to thefront face B of the heel part, but leaving a portion M, of wood, unitingthe two sides of the heel part at its front upper corner. The heel-partplate D, jack-pin socket I, and the anvil-heel seat N are all preferablyformed in one piece and when so made are formed, preferably, by forging.Back of the portion where the fore-part plate overlaps the heel-partplate the forging is made as thick as the two plates together,thusforming a web 0, uniting the heel-part plate to the j ack-pin socket.The web 0 is extended down to the top of the anvil-heel seat N. Ablock Pon the web fills the slot from the front wall of the anvil-heel seat Nto the vertical wall 13 of the heel part. A pin of wood Q is glued intoholes in the parts B and B of the heel part,which are separated by theslot Win the heel part, and this pin passes through an alined hole 0 inthe web 0. The pin Q, fastens the forging in the heel part and firmlyunites the wood of the front lower portions B and B of the heel part Bwhere they are separated by the web 0. The anvil-heel seat N is formedseparately from the jack-pin socket I, so that such heel-seats ofdifferent sizes and styles can be used with the same hinge mechanism.The jack-pin socket I is formed with a flaring portion I. near its lowerend, which portion forms a shonlder,against which the anvil-heel seat Ncan firmly rest. Below the flaring portion 1' of the jack-pin socket Iis a cylindrical portion 1 at the lower end of which is an annular lip IThe anvil-heel seat N is provided with a circular countersunk hole N. Infastening the anvil-heel seat it is placed over the lower cylindricalend I of the jack-pin socket I and against elliptical in verticalcross-section.

the shoulder formed by the flaring portion I. The lower end I of thejack-pin socket M is then expanded or upset in the countersunk hole N inthe anvil-heel seat N. To provide for the heel-tack of the insole, aplug of wood R is dropped into the lower end of the anvilheel seat N andis fastened in place by turning the annularlip 1 before mentioned. Theweb 0 affords a support for the front portion of the anvil-heel seat N,and. the block P prevents its turning on the jack-pin socket I.

A locking-piece S occupies the slots G and G in the fore and heel partplates 0 and D and serves to lock the parts A and B of the last bothagainst strains tending to collapse the last and against strains tendingto move the said parts away from each other beyond their normalposition. The locking-piece also acts to extend the last. Saidlocking-piece S con sists of a preferably-cylindrical pin S, occupyingthe slots G and G in the fore and heel part plates and connecting twoparallel arms S and S which are enlarged at their forward ends S Thefore part A is cut out ateach side of the slot A to allow thelocking-piece arms S to play. The arms S are for the purpose ofaffording convenient means to move the locking-pin S, and for thatpurpose such arms S are most conveniently maintained in asubstantially-horizontal position. The op-' posite faces S and S of thearms S and their enlarged ends S and S are in parallel planes and serveto hold the fore and heel part plates 0 and D together, thereby greatlystiffening or bracing them. The said faces S of the arms S are cut awayat their middle portions S to reduce the friction on the plates. Therearends S of the arms S play between alined lugs 0 and 0 formed onopposite sides of the web 0, and the ends of a pin T, driven through ahole in the web 0. The locking-piece S is combined with the hinge-platesA and B by holding it with its arms S and S extended upward andthreading one arm S through the superposed slots G and G in the plates 0and D, preferably before the rivet F is put in place which forms thepivot of thehinge. The arms S and S of the locking-piece are then swungdown to their normal position to rest on the lugs O and O on the web 0,and the pin T is driven into the hole in the web. If the upper and lowersurfaces of the arms S and S are parallel, the pin T and lugs O and 0must be somewhat farther apart than the vertical thickness of the arms Sand S; but a close fit may be had by making the arms S and S It will beseen that this locking-piece S can be forged at a single operation andrequires no further finishing. The locking-piece S can, if desired, bemade flaring at each end like the rivet F and the walls of the slots Gand G be countersunk, in which case the locking-piece ends can be flushwith the outer surfaces of the plates 0 and D and need not projectbeyond them.

Itis desirable to have the last automatic- The particular means employedconsist of a spring or springs U and U, preferablyone on each side ofthe web, which rest on the block P at the bottom of the web 0, extend ina curve around the wooden plug Q, and then extend forward and upward,where their upper ends are inserted in notches in the forward portionsof the lower faces of the arms S and S of the locking-pieces S.

The tops of'the slots G and G are so positioned with reference to thecenter I) of the hinge that when the pin S of the lockingpiece Soccupies and consequently alines them the last parts are in normalextended position. When the pin S of the lockingpiece S is at the top ofthe slots G and G, the last is locked, for the pin is then in a portionof the slots where the walls are parallel and where they canconsequently have no tendency to cam the pin to another position. Thecurve or curves at the bottoms of the slots G and G are full enough sothat the pin S of the locking-piece S can remain between these curvedwalls G and G, and at the bottomof the slots when the last is collapsed.The curvature of the curved wall or walls G and G of the slots is suchthat when the pin S of the locking-piece S is forcibly raised it,through its action on the curved wall or walls G and 'G is caused toforce the fore and heel part platesG and D apart, throwing the heel partB back into extended position and locking the last. I can, if desired,form the cam-surface G which serves to extend the last, di-' rectly onone of the last parts Aor B instead of on the connecting mechanismbetween these parts. 1

I have shown the locking-piece S as having a movement away from thehinge center b to lock the last and as having a movement toward suchcenter I) to unlock the last; but these movements could by properlyshaping the slots G and G easily be reversed so that the locking-piece Sshould move toward the hinge center I) to lock the last and away fromthe center to unlock the last. I can also make the locking-piece Sseparate from the fore and heel part plates 0 and D-for instance, in theform of a pin or plugand can lock the last by passing such pin betweensurfaces or into openings or notches on the plates 0 and D after thelast has been extended, or by tapering such pin or plug I can extend thelast in the act of inserting the plug between said surfaces or into thesaid openings or notches. The plug can either be a connected part of themechanism or can be entirely separate and removable, so that it isguided by the hand in being placed in position in the last. I candispense with one plate 0 or D,

using a single plate and using any of the above-described locking piecesor arrangements thereof.

The plates 0 and D in any or all of the forms described and used withany or all of the described forms of slots, locking-pieces, springs,&c., are capable of use in other relations.

The last shown in Fig. 15 differs from the last shown in the previousfigures only as regards its locking-piece and the actuatingspringtherefor. This locking-piece V consists principally of a cylindrical pinV, connecting two parallel arms V and V having vertical faces V and Vthat hold between them the hinge-plates. The vertical faces V and V ofthe parallel arms arecut away along their central portions V and V toreduce the friction. At their rear ends the arms V and V are providedwith alined holes V and V through which holes and a roller V a pin V isthrust, after which its ends are headed over. This roller V travels in aslot G, formed in the heel-part hinge-plate W. On each side of thehinge-plate W a notched lug W is formed, in which rests one end of aspring X, the other end of which engages a notch V in one of the arms Vof the lockin g-piece V. The connection between the rear ends of thearms V and V gives them greater strength to hold the fore and heel partplates against each other.

The operation of the form of last shown in the drawings is as follows:In the normal position of the last, into which position the parts of thelast are thrown by the spring, the locking-piece S, owing also to theaction of the spring, is at the top of the slots G and G.

'When it is desired to remove the last from a shoe, the locking-piece Sis forced toward the hinge center 17 against the action of the springs Uand U and the fore and heel parts A and B are swung toward each other,thus materially shortening the last, and the last is withdrawn fromtheshoe. As soon as the last is released the springs U and U throw thelocking-piece S upward, which latter by its action on the curved walls Gand G of the slots G and G swings the fore and heel part plates 0 and Dapart and with them the fore and heel parts A and B and extends thelast. The locking-piece S then passes above the curved walls G and G andbetween the parallel straight walls, in which position it locks thelast, thus automatically restoring it to proper position for having theparts of a shoe assembled thereon. If it is desired to insert the lastinto a finished or partly-finished shoe, the locking-piece S is forcedfar enough down in the slots G and Gabout half-way for the curved wallsG and G to properly engage the pin S of the locking-piece S, when, ifthe heel part B be thrown toward the fore part A, the curved walls G andG will throw the pin Sof the locking-piece S the remainder of thedistance to the bottom of the slots G and G. The last being nowcollapsed can be inserted into the shoe. If the springs U and U shouldnot be strong enough to raise the locking-piece S and extend the last, ahook can be inserted into the recess between the fore and heel parts Aand B and the locking-piece S be raised, or pressure can be applied tothe heel part B to force it into extended position, and the springs Uand U will raise the locking-piece S to locking position during suchmovement of the heel part. When it is desired to detach the fore part A,the end E of the spring E on the wedge E, by means of the fingersapplied to the handle E on the wedge E, is raised out of the notch inthe fore-part plate 0 and the wedge E is turned toward the heel part Band about the center of the arc-shaped flange C until the flange E onthe wedge E is disengaged from the circular edge of the fore-part plateG, when the wedge E can be lifted out of the slot A in the fore part A.The fore part A is now moved laterally until the arc-shaped flange O onthe fore-part plate is disengaged from the arc-shaped groove A in thefore-part slot A when the fore part A can be moved forward until it isclear of the fore-part plate 0. A reversal of these steps will fastenthe fore part on the fore-part plate. It will be observed that the forepart does not require that any metal part be fastened permanently to it,so that there is no metal part to be furnished with a new fore part. Thewedge which fastens the fore-part plate into the fore part can, ifdesired, be fastened in place merely by the friction caused by forcingit home, thus dispensing with the spring-catch on the wedge, which catchengages the notch on the fore-part plate.

It will be observed that my connection between the fore and heel partsis such that the center of motion of the hinge does not have to occupyany precise relation to the heel and toe of the last, and consequentlyany size or shape of fore part can be used with a particular heel part.It will also be observed that, since the only requirement as to thetransverse recess is that enough material shall be removed to allow thelast to collapse to the desired extent, I am enabled to preserve theentire instep-curve on the top of the fore part, which is an advantagein assembling the parts of the shoe on the last in performing theoperation of lasting the shoe and in removing the shoe from the last.
